LIQUID-GUN.

Application filed December 16, 1915.

To all whom t may convenir.

Be it known that I, CHARLES F. Lnrnvnn, a citizen of the United States of America, residing at Plymouth, in the county of Wayne and State of Michigan, have invented certain new and useful lmprove-` ments in Liquid-Guns, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to liquid guns of that type in which the discharge of the liquid is eected by the telescopic collapsing of the barrel.

It is the particular object of the present invention to obtain an increased volume of discharged liquid without necessitating any increase in the movement of the barrel, and to this end the invention comprises thel construction as hereinafter set forth.

1n the drawings: Figure 1 is a longitudinal section through the gun, shown as a liquid pistol; Fig. 2 is a cross section on line :1a-m Fig. 1; and Fig. 3 is a view similar to Fig. 1, showing the loaded position.

A is the frame member, which is formed of a sheet-metal stamping, comprising a barrel section B and an integral handle section C D is a telescopic extension of the barrel B, which also is preferably formed of a sheet-metal stamping having integral therewith a trigger and guard section E formed by parallelly-arranged spaced v plates or flanges.

F is a magazine barrel arranged within the extension barrel D, being provided at its forward end with a central discharge aperture Gr, and H is a piston itting said barrel and relatively movable to draw in and to eject the liquid.

1n collapsing the telescopic barrels through the actuation of the trigger the magazine barrel F will also be moved, and in case the piston H is attached to the lstationary member A, thiswill effect a displacement of the liquid contents. The amount of movement, however, is limited to the stroke of the trigger. To increase the discharge have provided means for multiplying the relative movement of the barrel and iston, preferably constructed as follows: is a rod connected to the piston H and extending rearward therefrom. J is a lever connected at its upper end to the rod 1 and iulcrumed at its lower end upon Specification of Letters Patent.

a pivot K extending between the parallel side plates of the trigger section. L is a link pivotally connected at one end to the lever J and at its opposite end to a pivot M secured to the frame member A. The construction ]'ust described is such that whenever the trigger section E is drawn inward, thereby carrying with it the barrels D and F, the lever J will be rocked upon its fulcrum, which will cause an opposite movement of the rod I and piston H. Furthermore, by arranging the pivotal connection between the link L and lever J at a point nearer the ulcrum K than the connection to the rod l, a multiplying movement is imparted to the latter, so that the travel of the 'piston is in excess of the travel of the cylinder. This `will yincrease the capacity of the cylinder and permit of either discharging the same in a single shot or by a succession of shots, each being effected by a partial mofement of the trigger. l f

What 1 claim as my invention is 1. A liquid gun, comprising a liquid barrel and cooperating piston, a trigger connected to the one for actuating the same, and a multiplying lever connection between said trigger and the other.

2. 1n a liquid gun, the combination with a liquid-containing barrel and a coperating piston, of a telescopically-collapsible false barrel in which said liquid barrel and piston are arranged, a trigger for collapsing said false barrel, and a lever connection actuated by said trigger for imparting a multiplied relative movement to said liquid `bar rel and piston.

3. 1n a liquid gun, the combination with a telescopically-collapsible false barrel, of a liquid-containing barrel and cooperating piston therein, a frame and a trigger connected respectively to the members of said telescopic barrel, and a lever mechanism connected to said frame and trigger for imparting a multiplied relative movement to said liquid-containing barrel and piston.

4. In a liquid gun, the combination with a telescopically-collapsible barrel, of a frame connected to one of the telescoping members and a trigger connected to the other, a liquid-containing barrel carried by the trigger section, a piston therein, and a multiplying lever actuated by said trigger section and connected to said piston.

5. 1n a liquid gun, the combination with 10 section-and plvotally connected thereto, be-

.forming a ng also connected to said piston, and a link fulcrum bearing for said lever connected with said frame.

In testimony whereof I ax my signature in presence of two witnees.
